UNrTED STATES PATENT OFFICE.

CHARLES A..ALLEN, OF CHICAGO, ILLINOIS.

VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 439,317, dated October 28, 1890. Application led September 17, 1889. Serial No. 324,246. (No model.)

To @ZZ whom tf/:troy concern."

Be it known that I, CHARLES A. ALLEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain `new and useful Improvements in a Perfuming-Case, of which the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this speciication.

The object of this invention is to provide a novel toilet article for the exhalation of perfumery, the nature of the device being such that it is more especiallyT adapted to be carried in the pocket or about the person. The device may also be used for the eXhalation or evaporation of liquid disinfectants, either for ordinary purposes or in the sick-room, by suspending the same from the wall or ceiling.

Figure 1 is a longitudinal section of a device embodying my improved features; Fig. 2, an elevation; Fig. 3, a transverse section in plane 3, Fig. 1, looking in the direction indicated by the arrows; and Fig. 4, a perspective of a wire frame used in supporting the absorbent material on the inside of the case.

Referring to the drawings, A represents the outer case; B, an inner case; C, the absorbent body, and D a wire frame for supporting the absorbent body on the inside of the case.

In the present application the device is of a cylindrical form, the two cylinders comprising the double walls being telescoped and made to iit closely together. The upper end of the inside cylinder or case is bent outwardly and downwardly over the corresponding end of the outside case, forming the annular overlapping flange ct, and the opposite or bottom end a of the inside case has the edge turned upwardly to form the flange a2, which overlaps the corresponding end of the outside case, thereby securing the two cylinders together against an endwise movement, but permitting of a rotary adjustment. The outside case is provided with a number of perforations a3 disposed at intervals in rows, as shown. The inside case is provided with a corresponding number of perforations a4. By turning-either one of the cylinders the rows of perforations maybe brought into the relative position illustrated in Fig. 3, whereby the case is tightly closed and the process of exhalation or evaporation stopped.

When the perforations in the two cylinders are brought into a coincident relation, coininunication is established between the interior of the case and the outer atmosphere. The perforations may be but partially uncovered, so that the evaporation or escape of the contents will be very gradual. In the upper end of the case is inserted the removable stopple E, provided with the inwardly projecting perforated lug b.

The absorbent body C will consist, ordinarily, of a piece of thick felt or other suitable material, and will be. of a less diameter and length than the inclosing-case for the purpose of leaving a clear air-space b all around, as shown in Figs. 1 and 3. The absorbent body is clamped in the wire frame D, one end of which is provided with the hook b2 to be inserted in the perforated lug b, and the absorbent body suspended in the case, as shown in Fig. 1. One or more wires d may be bent around the absorbent body, leaving the ends projecting (see Fig. 4) so as to bear against the interior inclosing sides of the case, as shown in Fig. 1, and keep the absorbent body away from contact therewith, thus preventing the liquid from escaping in the form of drops or by too rapid evaporation.

In taking out the Pstopple the absorbent body is removed at the same time, when the material may be charged or saturated `with the perfume or other liquid.

When the particular use of the device is such that the process of evaporation is to be continuous, then but one cylinder is necessary and the double construction may be dispensed with.

In making the device of a single thickness any shape other thanV cylindrical may be adopted-such as oval, dat, half-round, heartshaped, and so on-for the better convenience of carrying the article in the pocket.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent. is

1. A perfuming-case consisting of two cylinders, one tting closely within the other,

ICO

and each provided with a number of perforations so disposed that by rotating one of said cylinders with reference to the other said perforations may be closed or brought into coinaident relation, and an absorbentbody supported inside of said case, substantially as and for the purpose set forth.

2. The combination of the double cylindrical oase, closed at both ends, perforated as described, and having alternate overlapping ends, whereby one cylinder may be rotated with reference to the other, but are looked against an endwise movement, and the absorbent body inserted in said case and sup ported out of Contact with the inelosing sides thereof, substantially as and for the purpose set forth. f

3. The combination, with the double oyhndrical ease perforated as described, of an absorbent body inolosed therein and of a less CHARLES A. ALLEN. Witnesses:
